North Sea and West of Scotland
Abstract:
Data used to produce figures come from the STECF working group on Fisheries Dependent Informations . Please note that time series might be incomplete for some countries/indicators.
You can check 
if data were provide or not for a couple of country/year.
Landings
The DiscardLess case study is primarily directed towards the fisheries in the North and Western parts of the North Sea, with scientists from Denmark and UK being the main participant in the project. Given the linkages between fisheries East and West of Scotland, the entire NorthWestern area is considered together, eventhough they belong to different ecoregions.
The North Sea (ICES subdivision IVa,
IVb and
IVc
) and West of Scotland (ICES subdivision
VIa
) has an average depth around 100 meters. It is a temperate coastal shelf sea with a deep channel in the northwest, a permanently thermally mixed water column in the
south and east, and seasonal stratification in the north. A detailed description of the North Sea ecosystem is available from the ICES Ecosystem Overview

The French landings (in volumes) are mainly made by dredgers fishing for scallops, followed by pelagic trawlers targeting mostly herring and horse mackerel, the bottom trawlers are fishing on a mix of demersal species some of them being under TACs (plaice, sole, cod, whiting) and others not (red mullet, squids…). Trammel net are also targeting demersal species with a focus on flat fish.

Discards
Discarding in the area is relatively high (around 27% of the demersal catches in 2014), due to the mixed nature of the fisheries. There are several causes of discards, including Minimum Landing Size, low economic importance and/or shortage of quota. For a more in-depth analysis of discard patterns, see the 2014 Discard Atlas produced for the North Sea and for the West of Scotland

Disclaimer : Following graphs are made using discards rates at high spatial level and the landings at statistical rectangle level as raising factor. We assume that it's not the more statistically consistent way to proceed. However we consider that, with available data, it's a first step to use the data.
